i don't understand what any Laura would do as an EMT. That is absolutely not anything she's ever shown interest in. Or, to be honest, any skill at. She's been portrayed as oblivious to the emotional or psychological needs of herself or others, if not outright callous and uncaring for anyone who thought they were her friend.
And the problem with Synch is that they made him plot breaking. You have one guy with the powers of Jean, Xavier, Proteus, Exodus, Magneto, Rogue, Destiny, and all the other Omega's and high Alphas he's mingled with...and that's just to start! He also has the Venom Symbiate and everyone else's powers, too. But...for some inexplicable reason (bad writers and writing), he's moping around a dank dirty sewer wondering, 'My oh my, what can I do to help Mutants...?'
It's like X-Office isn't even trying anymore!
